IMPROVED BABY-JUMPER.

The Schedule referred to in these Letters Patent and making part of thesame.

To all whom 'it may concern Be it known that we, WILLIAM BERG andMATHIAS STEPHAN, of Canton, in the county of Stark, and State of Ohio,have invented certain new and useful Improvements in Baby-Jumpers; andthat the following is a full, clear, and exact description of the same,reference being had to the accompanying drawings, making a part of thisspecication, in which- Fignre 1 represents a perspective view of thejumper.

Figure 2 represents a longitudinal vertical section through the same.

Similar letters of reference, where they occur in the separate figures,denote like parts of the contrivance in both.

` Our invention relates to a baby-jumper, in which the lever andspring-seat have au adjustment in their supports, or fulcra, and areconnected toa leaf-spring,

by a yielding link, as will be explained,

To enable those skilled in the art to make and use our invention, wewill proceed to describe the same with reference to the drawings. v

A represents a base, or: frame, upon which the bahyjumper is arn nged,said frame being so made as to rest firmly upon the floor or othersmooth or even surface.

At the front part of the frame there is arranged and firmly secured asupport, B, through an opening in the top of which is placed the leverC, whiohhas, uponits long arm, a seat, D, and its short arm is connectedby a link, E, to a leaf-spring, F, that is fastened to the base A, andprojects ltherefrom, as shown in the drawlngs.

Upon the under side of that portion of the lever C that is to rest uponthe supports, or fulcra B, there is a notched plate, e, which can beshifted and supported upon the bearer B, and thus .regulate the Weightin the seat D to the force of the spring.

The spring we have is composed of two leaves, and is fastened to thebase at b b. There may be more than two leaves, and one may serve a verygood purpose, but we prefer two.

On the end of the lever -O is placed, by way of ornament, al horse head,G, and the link E is united to this ornament.V The linkmust he yielding,so that it will work in connection with the spring, whether theleverseat be. moved forward or back in its bearer B, to adapt the weightin the seat to the capacity of the spring.

Reinsc c, extend from the horses headto the seat D, though these are notessential to the machine.

Having thus fully described our invention,

What we claim therein as new, and desire to secure by Letters Patent, is

The combination of the base, bearer, notched plate, lever, link, andspring, arranged and operating together, substantially'in the manner andfor the purpose herein described and represented. y
